摘　　要：在阐述农业非点源污染的概念、危害和特征的基础上,分析了国内外目前农业非点源污染模型研究的特点,指出以元胞自动机为代表的时空动态模拟模型已经在农业非点源污染的研究中展现出强大的生命力,可以认为是农业非点源污染模型研究的第四个阶段。最后总结了现有农业非点源污染模型的不足之处及未来的发展方向。This paper clarifies the concept,harmfulness and characteristic of nonpoint-source agricultural pollution,detailedly analyzes the characteristics of the current researches on nonpoint-source agricultural pollution models at home and abroad, and points out that the spatio-temporal dynamic simulation models whose representative is the cellular automata have exhibited an extensive applicabil- ity,which can be considered as the 4th stage of researching into nonpoint-source agricultural pollution models. At last the paper summarizes the deficiencies and development direction of existent nonpointsource agricultural pollution models.
